Page 10 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process CIM Issues Process consists of three primary components: o Issues Submission o Issues Resolution o Issues Tracking

Page 11 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Submission CIM Issues Submission o In the past issues have been written second hand from information in s, discussions at Interop Tests, etc. o Consequently, issues that could not be resolved quickly are frequently difficult to interpret when coming back to them. o Currently requiring issues to be written by the submitter, preferably using the CIM Users Group website.

Page 15 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Submission New Issue Submission Form

Page 16 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Submission Tips for CIM Issues Submission o Be as specific and detailed as possible. o If possible, include a detailed proposed resolution to the issue. A UML model or UML class diagram can be submitted with the issue as an attachment. o For proposed model extensions include a detailed use case. o Review the CIM issues spreadsheet before submitting to determine is the issue has been submitted previously.

Page 17 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Submission CIM Naming Rules*: o Class names are UpperCamelCase (GeneratingUnit). o Attribute names are lowerCamelCase (raiseRampRate). o Association role names are UpperCamelCase. o Association role names are required, but association names are not. o Names shall be singular unless the concept is plural. o Names shall not include a unit name (“ratedVoltage”, not “ratedKV”). o Attribute names shall not include the class name. *(sample list, not exhaustive)

Page 18 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Submission CIM Naming Rules (cont’d)*: o Use of abbreviations is allowed, but not recommended. o Acronyms can be used, but the expanded terms must be included in the definition. o Association role names should use the corresponding end side class as the base role name. *(sample list, not exhaustive)

Page 19 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Submission CIM Issues Spreadsheet includes fields for: o Working Group (WG 13, WG 14, WG 16 or combined) o Issue No. (Unique # assigned by CMM) o Author / Contact Information o Date Submitted o Package (Wires, Core, Assets, etc.) o Description of Issue o Proposed Resolution o Decision o Person Assigned o Due Date Status

Page 20 Copyright © Siemens Energy, Inc All rights reserved. CMM Report CIM Issues Process - Resolution CIM Issues Resolution o Simple issues may be resolved by the CMM and then sent to WG 13 members for approval. o More complex issues will be discussed during WG 13 and WG 14 CIM issues conference calls. Resolution of an issue may be reached during calls or may be deferred to the next WG 13 or WG 14 meeting. o Complex or controversial issues will be discussed face to face at WG 13 and WG 14 meetings. o All WG 13 CIM changes are tracked in a spreadsheet.
